Comment for lw-map.dtd and lw-topic.dtd on adding filtering attributes

for consideration:

<--You can add filtering attributes
(specialised from the props attribute)
to the document type by declaring them
here. 
You can uncomment the section and change
"ADD-ATTRIBUTE-HERE to the name 
of the attribute you want added to the
document type.
You will also need to declare your use
of the attribute in the included-domains entity.-->
